A portable application can be run from a removable drive (USB flash drive, iPod, portable hard drive, etc) on any Windows computer without installation.
You will carry the program with settings on removable drive and don't modify settings on host computer.
On Vista and above turn off User Account Control (UAC) or run launcher as admin.

If you let the installers of Chrome and Java use the default path you should have:X:\PortableApps\CommonFiles\Java\bin\plugin2\npjp2.dllfor Java plugin dll andX:\PortableApps\ChromePortable\ChromePortable.exefor ChromePortable launcher.(ChromePortable and CommonFiles must be in the same parent folder).

But there is a problem if you test: Chrome says plugin is obsolete and you have to choose run anyway.

Hello!Thank you very much for all your efforts and all your work on the portable appz project.this is a long time that i was looking to find a way to send you some feedbacks.i would like to ask or suggest if it is possible to make the on-line portable launcher to find or load the requested file from the local storage in a case that i already have it instead of redownloading the file. also is it possible to tell to the launcher to repack the portable installer after the download and extraction is complete or located, so we will get a full off-line installer.

Hi Bernat, thanks for great work in the blog. I have a question: How I can do portable java? I downloaded the latest version 7 update 10, I extracted it, and I copied all files in the path where your launcher made the program portable, but It doesn't run. And there are a posibility that you create a launcher of java 6 update 38, because JDownloader 0.9.581 (portable) only works fine with java 6, not with java 7 (source: Jdownloader forum).

Yes, you are right, I updated the name of file .ini, I observed when I run JDownloader (0.9.581 and 2 beta), the process of java never starts. (Tested with java 6 update 38 and 7 update 10, by copying all files into the path of the previous portable versions).

Ops... I didn't unpack the files with extension pack, there were my problem, now I know for the next time. And thanks for the update, I tested the differents versions of java and are working fine. Thanks a lot for your time and for your great effort to keep it up.

Hi BernatI could not use Java 7 Online because it says "Forbidden"I downloaded both setup files manually and i have these now:Java_Portable_7.0.750.13_32-64_bit_Online.exejre-7u75-windows-i586.exejre-7u75-windows-x64.exe. Just I have request that please modify Java Online file to first of all looks at current folder and locates to jre-7u75-windows-i586.exe and -or- jre-7u75-windows-x64.exe files and uses theme to make Java Portable versionThanks
